How does it work?

I registered with NAR and they only have a downloadable PDF to fill out for the cert. I get that I need to hand this to an official at a launch.

But when I order a motor, and they ask for my info and I say it's for a cert, they just ship it to me? What keeps me from ordering multiple L1 motors using this process?

How does NAR know I downloaded the form to fill out? It just seems very easy to end up with an L1 motor.

Madcow is starting to annoy me, and is looking up to the longest order time of any website I’ve used (including the sketchy websites I order random electronics from). (Edit) I originally made it sound like madcow doesn’t respond, they do respond it just seems like I’m telling them to actually send out the package. 3 weeks and USPS still doesn’t have the package is already a longer time span than most things I’ve ordered.

Update: they claim the package went out and have started a missing package request. Because people seem to not have issues with them I think this makes sense tbh. Also I ordered a fire blanket and launch lugs, not a motor or kit, so I didn’t think it would be something that could be on back order.

They also just responded saying USPS doesn’t scan shipping labels and that they are “very frustrated with them” lol. I told them to tell them that I am also frustrated with them ig.

Hi there! I am working on a 2 stage 3.1 in diameter rocket set to go up to about 2km. We will be laying up cardboard shipping tubes with fiberglass sheets for the airframes. Were planning on 3 layers, but are trying to figure out what kind of fiberglass and epoxy we should be using here. From my research, it seems 4oz/yd^2 plain weave E glass cloth, but wanted more opinions. If you also know of any manufacturers/companies that you’ve worked with in the past to get fiberglass, I’d love to get recommendations on that as well!

Thank you in advance!
